Looking at the specs of the ND-3540A it's clear that NEC was looking to create a very fast DVD writer. Both DVD+R and DVD-R discs are burned at 16x, while DVD+R DL media can be written at 8x and DVD-R DL discs will burn at 6x. For DVD+RW the ND-3540A is rated at 8x and it can write DVD- RW media at 6x. CD performance is up there with the best too, with 48x CD- R and 32x CD-RW ratings.
